EPIDEMIOLOGICAL AND PATHOLOGICAL PROFILE OF SKIN ADNEXAL TUMORS: STUDY OF 97 CASES

The Adnexal skin tumor is one of the most uncommon types of tumors. It could display multiple differentiation such as follicular, eccrine, apocrine, sebaceous and sometimes mixed differentiation; generating a mistaken diagnosis. The world health organization differentiated in 2018, adnexal skin tumor to 2 major subtypes: 21 benign and 15 malignant. A fourteen year retrospective case study was carried in the anatomy-Pathology Laboratory of the University Hospital Mohammed VI in Marrakesh-Morocco; from January 2004 to September 2019. This study aimed to describe the epidemiological and pathological profiles of skin adnexal tumors. Among 97 patients admitted for consultation with a skin mass in different locations, 97 of them were diagnosed with skin adnexal tumors. The epidemiological results displayed a sex ratio of 1.15 with a male predominance 52 cases (53.6%) and 45 cases (46.4%) for women. The anatomy -pathology analysis showed that benign tumors represented 93 of the cases (95.9%) while malignant tumors represented only 4 cases (4.1%): two cases of porocarcinoma and two of sweat gland carcinoma. Tumor differentiation was follicular in 50 cases (51.6%), eccrine / apocrine in 44 cases (45.3%) and sebaceous in 3 cases (3.1%).
